在edittext字段1和2中输入数据后更新TextView

Question

我正在使用Tablelayout，我正在实际添加5行。 每行有4列，在pos 0的Textview描述，2 edittext尝试＆amp;在pos 1和2处制作了视图，最后在pos 3处制作了TextView pct。 当用户在编辑文本尝试中提供输入时，我只想在textview pct中计算madeET / attemptET * 100和setText。

这是目前为止的当前代码。所需结果仅发生在第6行的最终输入中。我在addTextChangedListener以及madeET

上尝试了setOnFocusChangeListener

private void setTableRows(){
    String[] desc = new String[]{"Flat level putts","Uphill putts","Downhill putts","Left-to-right putts","Right-to-left putts"};
    int totalputts = 0;

    for (int i=0;i<desc.length;i++){
        TableRow tr = new TableRow(this);

        TextView descTV = new TextView(this);
        descTV.setText(desc[i]);
        descTV.setTag(i);
        descTV.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
        descTV.setPadding(5, 0, 0, 0);
        tr.addView(descTV);

        final TextView pctMade = new TextView(this);
        pctMade.setGravity(Gravity.CENTER);
        pctMade.setTag("pct"+i);
        //pctMade.setText(String.valueOf(pctmadecalc));
        pctMade.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
        pctMade.setPadding(5, 0, 0, 0);

        final EditText madeET = new EditText(this);
        madeET.setInputType(InputType.TYPE_CLASS_NUMBER);
        madeET.setTag("m"+i);
        madeET.setFilters(new InputFilter[]{new GolfAppUtils.InputFilterMinMax("0","10")});
        madeET.setGravity(Gravity.CENTER);
        madeET.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
        madeET.setPadding(5, 0, 0, 0);
        final int finalI = i;
        madeET.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                /*if(s.length() > 0){
                    double pctmadecalc = Integer.parseInt(s.toString()) / PUTTS_PER_CATEGORY;
                }*/
            }

            @Override

                pctMade.setText(null);

                    //float pctmadecalc = (((float)(Integer.parseInt(s.toString()))) / ((float) PUTTS_PER_CATEGORY)) * 100;
                    /*NumberFormat df = DecimalFormat.getInstance();

        madeET.setOnFocusChangeListener(new View.OnFocusChangeListener() {

提前感谢您的帮助

以下回应的解决方案

public void onTextChanged(CharSequence s, int start, int before, int count) {
                if (s.length() > 0) {
                    pctMade.setText("");
                    float pctmadecalc = ((float) Integer.parseInt(madeET.getText().toString()) /
                            ((float) Integer.parseInt(attemptET.getText().toString()))) * 100;
                    //Toast.makeText(getBaseContext(), String.valueOf(pctmadecalc), Toast.LENGTH_SHORT).show();
                    pctMade.setText(String.valueOf(String.format("%.2f", pctmadecalc)));
                    //pctMade.setText(calcPct());
                } else {
                    pctMade.setText("");
                }
            }

Answer 1

这将是：

 @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                pctMade.setText("");
                pctMade.setText(s);

                //etc..
            }
